Abstract: PURPOSE:To attain superior refractoriness and toughness by subjecting a cast bloom, in which Al-Mg-Ti compound oxides are dispersed, to heating/cooling type controlled rolling. CONSTITUTION:A molten steel, having a composition containing, by weight ratio, 0.04-0.20% C, 0.05-0.50% Si, 0.4-1.8% Mn, 0.4-1.0% Mo, 0.05-0.20% V, 0.004-0.015% N, and 0.005-0.025% Ti, is preliminarily deoxidized, by which the amount of dissolved oxygen is regulated to 0.003-O.015%. Then, an Fe-Al-Mg alloy is added and the amounts of Al and Mg are regulated to 0.005-0.015% and 0.001-0.010%, respectively. The molten steel is cast and cooled down to 900 deg.C at a rate of (0.5 to 20) deg.C/s, by which Al-Mg-Ti oxides of a size of <=3mum are incorporated into the resulating cast bloom by >=20pieces/mm<2>. Subsequently, the cast bloom is heated to 1100-1200'C and rolling is started, and then, water cooling is done until a bloom surface layer temp. of <=700 deg.C is reached and rolling is performed in the course of recuperation between passes. This process is repeated once or more. After the completion of rolling, cooling is done down to 650-400 deg.C at a rate of (1 to 20) deg.C/s, followed by air cooling.

Title: Telephone set
Inventor: KAMIMOTO YOSHIMI
IPC: H04M11/00
Filed: 1988-01-22
Abstract: PURPOSE:To attain conversation even when the device of an opponent, to which a telephone call is made, is a facsimile equipment by automatically sending a PRI-EOP signal when a CED signal is returned from the opponent device. CONSTITUTION:When the opponent device, to which the telephone call is made, is the facsimile equipment, a main control part 3 can decide that the opponent device is the facsimile equipment since the CED signal (which shows that the self-device is the facsimile) is returned. When the opponent device is judged as the facsimile equipment, the PRI-EOP signal, which is a conversation reserving signal, is transmitted from a signal generating part 6 to the opponent device. Accordingly, the opponent device rings an alarm for an operator intervention request. Then, when an operator responds to this alarm and hungs up a receiver, a line is connected and the conversation can be executed. Thus, even when the opponent device, to which the telephone call is made, is the facsimile equipment, the conversation can be executed.
